STP enough ?
I have to build up a redundant VMWARE System.
I have a Core Switch (5400ZL ) and 2 Devices 1910-48Port Gig Switches for the VMWARE Hosts.
I want to interconnect the 1910 Switches with a 2 Port Trunk on every Switch to make a fast connection between the Switches .
I want to connect every of the 1910 Switches with one Gigabit Port to the 5400 Core Switch to get full redundancy if one of the Host-Switches is faulty .
What is the last Job to avoid loops on this construction ?
Is it correct that that i have only to activate the STP Protocoll on every Switch to avoid loops ?? ,
or is there a way that i can the manage the trunk between the 1910 Switches to transport only traffic between these Switches
Regards
Christian

Re: STP enough ?
Hi,
u have to be sure that every switch use the same protocol. If u only use 3 Switches take rstp.
In the CLI:
conf t
spanning-tree
spanning-tree force-version rstp-operation
and if you want to be ensure that the 5400 is root typ this:
spanning-tree priority 0
thats it!

Re: STP enough ?
Hello Pourl,
the network is a wide area of nearly 50 Switches , all HP Products with different types from 6600 to 2920
and 3 Core Switches ..
But the only point where I need to connect Switches together and every switch single to one core switch
is the VMWARE System ...
Shuould I use RSTP also in this scenario ?
Could you explain the difference from "classic" STP to this RSTP what you prefer ?

Re: STP enough ?
RSTP is compatible to STP but is significant faster, there is no need for stp.
If this is the only loop constellation u can use RSTP.
BTW. u should configure each Port with a Server as follow:
spanning-tree <port-range> admin-edge-port
So no Switch will be expected and latency decreases. any spanning tree protocol is disabled for these ports. but never plug a switch to these ports, wheater u are sure that u dont build a loop.
